The present invention provides a wound coil made by winding a conductive wire (2) around a core (3), wherein the core (3) is shaped having a tapered part (11) in which the outside diameter of the core (3) gradually decreases so that the diameter of the conductive wire (2) wound around the core (3) is not constant but instead gradually decreases; and the tapered part (11) is not tapered so that the outside diameter of the core (3) decreases at a constant rate from a large proximal end to a small distal end of the tapered part (11), but rather the tapered part (11) is formed into a tapered shape wherein the rate of decrease in the outside diameter of the core (3) is gradually reduced from the large proximal end to the small distal end; i.e., the tapered part (11) decreases in diameter at a high rate at the proximal end, and decrease in diameter at a lower rate in the distal end than in the proximal end.

    摘要: This invention provides a rolling method and a rolling apparatus, for flat-rolled metal materials capable of stably producing flat-rolled metal materials not having, or having extremely little, camber. A rolling method for a flat-rolled metal material uses rolling equipment including a rolling mill and at least a pair of pinch rolls for clamping a rolled material on the exit side of the rolling mill having a mechanism in which either one, or both, of upper and lower roll assemblies have a mechanism for supporting a work roll by split backup rolls split into at least three segments in an axial direction, the split backup roll group having a construction for supporting both a vertical direction load and a rolling direction load acting on the contacting work roll and each of the split backup rolls independently having a load measuring device. The method comprises the steps of directly measuring, or calculating on the basis of a predetermined measurement value, either one, or both, of left-right balance of a rolling direction force acting on a rolled material from the pinch rolls and the left-right balance of a rolling direction force acting on the work roll of the rolling mill through the rolled material; and controlling a left-right swivelling component of a roll gap of the rolling mill on the basis of the measured value or the calculated value of the left-right balance of the rolling direction force.
